IU1WO 98/08708CA 02264312 1999-02-241VEHICULAR U - TURN INDI CATORBACKGROUND OF THE INVENTION1. FIELD OF THE INVENTIONThe present invention relates to vehicular signalingindicators, and more specifically, to indicators forsignaling the attempt of U-turn.2. DESCRIPTION OF THE PRIOR ARTWhile the statistical incidence of U—turns asopposed to left—hand turns in the course of operationof a ‘vehicle is extremely" rare, the incidence ofaccidents while making a U-turn is extremely high.For this reason most local ordinances rigorouslycontrol the frequency of tflturns in any stream oftraffic. Nonetheless, practicality dictates that someU—turns be permitted, particularly where the travelpath arrangement and topography preclude a safer andmore convenient change in direction of travel of thevehicle.Thus, although a U-turn is considered staticallydangerous a limited frequency thereof is tolerable dueto practical reasoning.One cause for the large statistical incidence of U-turn collisions is the lack of a perceptive indexbetween. an incipient U-turn and. a left—hand turn.Typically, a present day vehicle is equipped with turnsignals by which an operator of a vehicle advises theapproaching and following vehicles or passersby of theforthcoming turn. Such signalling devices, however,do not distinguish between a left—hand turn and a fullU-turn. Thus, it is difficult to anticipate that theturning vehicle is embarking on a U-turn rather thana left—hand. turn. It is noted that the laws ofPCT/U S97/ 14989IUIWO 98108708CA 02264312 1999-02-242physical dynamics require a substantially slower speedwhen executing a U-turn than when executing a simpleleft—hand turn. Furthermore, controlling the travelpath with some sort of sign/signal control systemseems to never provide a positive indication when a U-turn is proper or available.In the past, various devices have been used forsignaling a message at the rear of a vehicle.Exemplary teachings of such devices in automobiles areknown in the prior art. For example, U.S. Patent No.4,868,541, issued September 19, 1989, to Sullivan etal., discloses an all turn signal using’ a manualultrasonic sending unit and an ultrasonic receiver anddisplay unit stationed in the rear window of a car,the receiver display unit blocks a fair portion of therear view mirror field of View of the operator and theultrasonic system is subject to error due to amultiplicity of acoustical frequencies in a car. U.S.Patent No. 4,994,786, issued February 19, 1991, toSchaffer, discloses a series of lights in theperimeter of the mid car mounted third brake light,requiring complex wiring and linkage to the turnsignal. U.S. Patent No. 5,003,289, issued March 26,1991 to Roman, disclose a U-turn signal attachment forcars, having an adjustable bracket. U.S. Patent No.5,086,289, issued February 4, 1993, to Sullivan etal., discloses a U-turn signal displayed in the thirdbrake light centrally’ located. in the rear of Inostnewer cars; having an actuator cumbersomely coupled tothe standard turn signal shaft and having complexwiring via the steering column. U.S. Patent No.5,281,950, issued January 25, 1994, to Le, disclosesan add—on U-turn signal device having a control modulethat enlists the original equipment by recognizing anON—OFF—ON left—hand turn signal switching sequence,thereby displaying a U-turn lamp located in the rearwindow of the car. U.S. Patent No. 5,457,439, issuedPCT/U S97/ 14989IUICA 02264312 2001-09-213October 10, 1995, to Kuhn, discloses an automobiletravel condition indicator that displays to the driverof the auto if the vehicle is encroaching a zone ofinescapable vehicular danger. German patent documentno. 2,917,193, published November 15, 1979, and Francepatent document no. 2,507,981, published December 24,1982, each disclose basic right—left turn signals forcars.In addition, conventional traffic or road signs orsignals currently in widespread use do not adequatelydesignate when proper or safe to attempt to execute aU—turn. For example, U.S. Patent No. 4,084,339,issued April 18, 1978, to Peltier et al., discloses avariable roadway sign display using projected imagesand indicia onto a large screen for improving trafficflow/control. U.S. Patent No. 5,303,492, issued April19, 1994, to Nishio, discloses a road sign usingmaterials having highly reflective properties toilluminate legend symbols. U.S. Patent No. 5,363,092,issued November 8, 1994, to Starchevich, discloses aportable personal sign that allows the user toilluminate alternative "TAXI" or "HELP" signs. U.S.Patent No. 5,400,019, issued March 21, 1995, toRiscoe, Jr., and U.S. Patent No. 5,475,386, issuedDecember 12, 1995, to Luoma, each disclose a portabletraffic light, however, neither of which indicatesallowed U~turns. U.S. Patent No. 5,493,292, issuedFebruary 20, 1996, to Fanslow et al. discloses anautomatic "SLOW" or "STOP" changing sign, specificallyused in construction areas.None of the above inventions and patents, takeneither singly or in combination, is seen to describethe instant invention as claimed.SUMMARY OF THE INVENTIONThe invention is an indicator for designating a UVturn attempt. The indicator includes an actuator, andIUICA 02264312 2001-09-214control means responsive to the actuator forgenerating a control signal. The indicator has atleast three flashing means, each responsive to thecontrol signal. Each of the at least three flashingmeans has a predetermined disposition. Each of the atleast three U—shaped flashing means includes a U-shaped series of illuminating means for sequentiallyproducing a U—shaped lighting effect. The series ofilluminating means illuminate along the series so thatthe U—shaped flashing means flashes a U-turnindication by illuminating the U—shape in segments.Also part of the invention. is an indicator fordesignating a U-turn attempt, in combination with avehicle. The indicator includes actuator meansaccessible to an operator of the vehicle for actuatingthe indicator. Control means are responsive to theactuator means for generating a control signal. Aplurality‘ of flashing means are responsive to thecontrol signal for indicating a U-turn attempt. Theplurality of flashing means includes a first, second,and third flasher. Each flasher includes a U—shapedseries of illuminating" means for sequentiallyproducing a U—shaped lighting effect. The first U~shaped flasher has a non—inverted disposition, and ispositioned on the anterior of the vehicle. The secondU—shaped flasher has a lateral disposition, and ispositioned on the side of the vehicle. The third U-shaped flasher has an inverted disposition, and ispositioned on the posterior of the vehicle. Theseries of illuminating" means illuminate along theseries so that the U—shaped flashing means flashes aU-turn indication by illuminating the U—shape insegments.{U1CA 02264312 2001-09-215BRIEF DESCRIPTION OF THE DRAWINGSFig. 1 is a perspective view of a vehicle includingthe present invention.Fig. 2 is an elevational top view of Fig. 1 showingthe wiring arrangement of the present invention.Figs. 3A—3C, 4A~4C and 5A—5B are plan views ofvarious indicator arrangements for use on vehicles andsigns.Fig. 6 is an environmental view! of the presentinvention used in a vehicle travel path.Similar reference characters denote correspondingfeatures consistently throughout the attacheddrawings.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTSWhen the operator of a vehicle intends to make a U-turn, it is important that all on—coming (i.e.,approaching and following) traffic be advised of such.In addition, it is also necessary to inform the crosstraffic lane, so that another vehicle while executingthe "right on red" privilege will not be found in theimmediate collision position with the vehicle makingthe U—turn. Further, it is important that passersbybe aware of the vehicle making the U—turn.The present invention provides a clearly visible andidentifiable vehicular U—turn indication. Theinvention is used primarily by vehicles (including butnot limited to bicycles, mopeds, motorcycles,automobiles, buses, trucks, trailers, boats, yachts,ships, and the like) for indicating that a safe andproper U—turn is forthcoming. The inventionadditionally provides vehicles with an indication whensafe and proper to make a U—turn or change directionfrom a respective travel path (including but notlimited to roadways, intersections, docks, slips, andIU1CA 02264312 2001-09-216the like). Herein, the invention is disclosed incombination with automobiles and intersections; it isnoted however, that this is illustrative and does notlimit the scope intended by the following claims.Referring to Fig. 1, a vehicle 10 is shown havingthe U—turn indicator of the present invention. Thepresent invention places a plurality of indicators onthe respective vehicle. In this figure, a front oranterior indicator 12 is shown with respect to theleft/driver side head light. The anterior indicator12 is a series of illuminating members, such aslights, LEDS, or the like, that sequentiallyilluminate forming a non-inverted ’U’. Also, a rearor posterior indicator 16 (see Fig. 2) is associatedwith the third. brake, or the any other centrallylocated rear light. The posterior indicator 16 alsois a series of illuminating members, such as lights,LEDs, or the like, that sequentially illuminateforming an inverted ’U’. In addition, a sideindicator 14 is shown with respect to the left/driverside turn signal light. Likewise, the side indicator14 is a series of illuminating members, such aslights, LEDS, or the like, that sequentiallyilluminate forming a ’U' having a lateral disposition.The anterior indicator 12 and the side indicator 14provide a clear indication to the on~coming traffic,the traffic in the crossing lanes, as well as anypedestrians or passersby of the intent of the operatorof vehicle 10.Fig. 2 shows the basic wiring diagram of theinvention. The heart of the systen1 is a controlmodule 18. The control modules receives an actuationfrom an actuator or switch 20. The switch 20 iseasily accessible by the operator of the vehicle 10.Preferably, switch 20 ii; a floorboard mounted footswitch. In this way the operator uses his foot toactivate the U—turn indicator. This allows for theIU1CA 02264312 2001-09-217vehicle 10 to have one less cumbersome item he needsto manipulate by hand while operating the vehicle 10.Although, a foot switch is preferred, any operatoraccessible switch 20 is within the scope of theinvention. Once the control module 18 receivesactuation, a control signal is generated. Thegenerated control signal is then submitted to each ofthe U-turn indicators 12, 14, and 16.Referring to Fig. 6, a U—turn indicator according tothe present invention is shown in combination with thevehicular travel path. Located about intersection 60are actuators or vehicle sensors 62. When a vehicle10 is in the vicinity of an actuator 62, a controlmodule 64 responds to the actuators 62, specificallywhen vehicle 10 is in the left—hand turn lane. Thecontrol module 64 generates a control signal fortraffic control lights 66A on pole 66. Moreparticularly, the left—hand turn signal light has aconventional left turn indicator 68, and a Lfiturnindicator 70. The control module 64 accumulates allof the positions of vehicles about the intersection 60from the actuators 62, and determines whether a U—turnis proper or safe. If the control module determinesthat a U—turn can be safely completed, indicator 70will illuminate in accordance with the presentinvention. It should be appreciated that the scope ofthe U—turn indicator, shown in Fig. 6 as a permanentintersection structure, is equally effective as aportable unit for servicing temporary and/or urgenttravel path alterations. For example, in a areas ofroad work or road construction, where access isrestricted or limited, a portable U—turn indicator canbe used in the same fashion as the permanent structureshown in Fig. 6, giving motorists the ability to altertheir respective travel direction safely, and withease. Even for aquatic crafts, the portable U turnindicator, on a suitable floatation device or pier,IU1CA 02264312 2001-09-218can direct aquatic traffic. For example, boat racecourses or directing docking maneuvers in low tides,to name a few.Fig. 3A, 3B, and 3C illustrate how the series oflight members are arranged in one aspect of theinvention. Fig. 3A has a rectangular light lens 30A.Internally, of the lens 30A a series of light members32A each having a circular shape, upon activation bya control signal, light members 32A will illuminatesequentially until the ’U’ is formed, turn off andrepeat the sequence until the U—turn is completed.Likewise, Figs. 3B and 3C operate in the same fashion,whereas Fig. 3B, light members are shown asrectangular elements, and Fig. 3C the lens 30C iscircular. Also, although not shown, each of Figs. 3A,3B, and 3C may be inverted in order to have aninverted U—turn indicator.Fig. 4A, 4B, and 4C illustrate how the series oflight members are arranged in one aspect of theinvention. Fig. 4A has a rectangular light lens 40A.Externally, of the lens 40A there is a series of lightmembers 42A, each having a circular shape. Uponactivation by a control signal, light members 42A willilluminate sequentially until the ’U’ is formed, thenturn off, and then repeat the sequence until the U-turn is completed. Likewise, Figs. 4B and 4C operatein the same fashion; in Fig. 4B, light members areshown as rectangular elements, and Fig. 4C the lens40C is circular. Also, although not shown, each ofFigs. 4A, 4B, and 4C may be inverted in order to havean inverted U—turn indicator.Referring to Figs. 5A and 5B, the lateral U turnindicators which are associated with the side turnsignals are shown. Specifically, a turn signal lensSOA or SOB is conventionally provided on the side ofthe vehicle 10. The U-turn indicator of the presentinvention is positioned as a lateral ’U’. LightlU'|CA 02264312 2001-09-219members SOA may have a circular shape, or lightmembers 50B may have a rectangular shape. Inaddition, the light members may also be positioninternally of the lens 50A or externally of the lensSOB. The specific arrangement is solely at thediscretion of the skilled artisan.It is to be understood that the present invention isnot limited to the sole embodiment described above,but encompasses any and all embodiments within thescope of the following claims.,1 M...— .... -..-.........
